Furthermore, our periodogram analysis of the precise RVs shows strong evidence for a short-period Doppler signal in the residuals of a two-planet Keplerian fit, which we interpret as a third, Saturn-mass planet with \r\n \r\n\r\n\r\n mdsini\r\n \r\n = \r\n \r\n\r\n\r\n 0.20−0.03+0.02\r\n \r\n \r\n M\r\n Jup in a close-in orbit with an orbital period of P\r\n d = \r\n \r\n\r\n\r\n 89.9−0.1+0.1\r\n \r\n days. We study the dynamical behavior of the three-planet system configuration with an N-body integration scheme, finding it to be long-term stable with the planets alternating between low and moderate eccentricity episodes. We also perform N-body simulations, including stellar evolution and second-order dynamical effects such as planet–stellar tides and stellar mass loss on the way to the white dwarf phase. We find that planets HD 33142b, c, and d are likely to be engulfed near the tip of the red giant branch phase due to tidal migration.

To investigate and understand their physical nature, detailed spectral information and accurate stellar models are needed. We use a new synthetic atmosphere model generation and compare model spectra to observations. To test the model accuracy, we compared the models to four benchmark stars with atmospheric parameters for which independent information from interferometric radius measurements is available. We used chi(2)-based methods to determine parameters from high-resolution spectroscopic observations. Our synthetic spectra are based on the new PHOENIX grid that uses the ACES description for the equation of state. This is a model generation expected to be especially suitable for the low-temperature atmospheres. We identified suitable spectral tracers of atmospheric parameters and determined the uncertainties in T-eff, log g, and [Fe/H] resulting from degeneracies between parameters and from shortcomings of the model atmospheres. The inherent uncertainties we find are sigma T-eff = 35 K, sigma(log g) = 0.14, and sigma([Fe/H]) = 0.11. The new model spectra achieve a reliable match to our observed data; our results for T-eff and log g are consistent with literature values to within 1 sigma. However, metallicities reported from earlier photometric and spectroscopic calibrations in some cases disagree with our results by more than 3 sigma. A possible explanation are systematic errors in earlier metallicity determinations that were based on insufficient descriptions of the cool atmospheres. At this point, however, we cannot definitely identify the reason for this discrepancy, but our analysis indicates that there is a large uncertainty in the accuracy of M-dwarf parameter estimates."],["dc.identifier.doi","10.1051/0004-6361/201322261"],["dc.identifier.isi","000371589800030"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/13431"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/41183"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Edp Sciences S A"],["dc.relation","info:eu-repo/grantAgreement/EC/FP7/279347/EU//WAVELENGTH STANDARDS"],["dc.relation.issn","1432-0746"],["dc.relation.orgunit","Fakultät für Physik"],["dc.title","Fundamental M-dwarf parameters from high-resolution spectra using PHOENIX ACES models I.
